Snap line and method

ABSTRACT

A snap line for use in applying powdered material to a surface. The line comprises at least one strand of material that has been coated with water repellent material. The line may be used in conjunction with powder that has also been coated with water repellent material. The line and the powder enable a user to apply lines to wet or damp surfaces in a normal fashion.

FIELD OF THE INVENTION

The present invention relates to construction equipment. Moreparticularly, the present invention relates to equipment that is used tolay out dimensional or building lines for workers in the constructionindustry.

BACKGROUND OF INVENTION

Snap lines have been used in the construction industry for many yearsfor laying out building or dimensional lines. They are easy to use,accurate, and inexpensive. Typically, a snap line is tautly heldadjacent or slightly above a surface that is to be marked. The line isthen pulled away from the surface and released so that it strikesagainst the surface, leaving a residual line of powdered material, suchas chalk. Over the years, snap line technology has evolved; powderedmaterial is now available in colors other than blue, and housings arebetter able to retain and protect the powdered material from theelements.

One thing that has not changed over the years, however, is the use andoperation of the snap line. That is, the snap line must still bepositioned adjacent or slightly above a surface to be marked, pulledaway, and then released so that it strikes against the surface to bemarked. This works quite well for most surfaces. However, a drawbackwith existing snap lines is that they are ineffective when weatherconditions are less than ideal.

As one may expect, conventional snap lines often do not operate asintended when conditions are wet or damp. Often, the powdered materialadheres to the snap line and does not release when the line strikes thesurface. Moreover, if some of the powdered material does manage torelease from the line upon impact, it does not easily transfer to asurface to be marked, and if transfer does occur, the powdered materialcan be easily smeared and/or washed away. Thus, whenever wet conditionsexist, layout work is essentially halted. This can be problematic inareas where wet conditions such as precipitation and high humidity arecommon.

SUMMARY OF THE INVENTION

A snap line for use in applying powdered material to a surface. The linecomprises at least one strand of material that has been treated withwater repellent material. The water repellant material may be applied tothe line by conventional techniques and technologies, such as sprayingand submersing. The line may be used with existing powdered materialssuch as the various colored chalks now in use, or it may be used inconjunction with powdered material that has also been treated with waterrepellent material. In combination, the treated line and powderedmaterial enable a user to apply lines to wet or damp surfaces, orsurfaces with shallow puddles thereon in a normal fashion.Advantageously, the treated line and/or powdered material may be usedwith most existing snap line.

Certain objects, features, and advantages of the present invention willbecome apparent from the following detailed description thereof taken inconjunction with the accompanying drawings, wherein like referencenumerals designate like elements throughout the several views.

DETAILED DESCRIPTION OF THE INVENTION

A typical snap line apparatus is depicted in FIG. 1. The apparatus 10includes a housing 12 for holding powdered material and an access door14 through which powdered material may be added without having todismantle the housing. The apparatus also has a rotatable handle 16 thatmay be pivoted between storage and use positions. The handle 16 isoperatively connected to a reel (not shown) about which a line 20 iswound. The line 20 includes an attachment ring 22, which is configuredto facilitate attachment of the line 20 to a suitably positionedfastening element (also not shown).

The powdered material used in snap lines is usually available in bulk asa stand-alone product. In addition, powdered material is packaged indifferently sized containers, of which a common size is 8-ounces. Whilethe preferred powdered material used in the present invention compriseschalk and/or cementitious dye, it is understood that other powderedmaterials may be used without departing from the spirit and scope of theinvention.

A process by which an improved powdered material may be treated is shownin FIG. 2. In the figure, a container 30 is depicted as having a cap 32,which has been removed to expose the powdered material 34 containedtherein. Another container 40 is also depicted as having its cap 42removed to expose water resistant material 44 contained therein. Asshown, the water resistant material 44 is added to the container 30.After an effective amount of water resistant material 44 has been added,and prior to mixing, the container 30 may be closed by reattaching thecap 32. Although the treated powdered material may be produced using anyone of a number of water resistant materials, it is preferred that thewater resistant materials are silicone based. More preferably, it hasbeen discovered that a particularly effective silicone-based waterresistant material is sold by KIWI Brands under the name of Cavalier®Protect-All™.

FIG. 3 illustrates another process by which an improved powderedmaterial may be treated. Here, a container 30 is depicted as having acap 32, which has been removed to expose the powdered material 34contained therein. Another container 50 is depicted as having a nozzle52, which directs water resistant material 54 (preferably Cavalier®Protect-All™) in a predetermined direction as it is expelled orpropelled from the container 50. As shown, the water resistant material54 is added to the container 30 by directing the water resistantmaterial onto the powdered material. Preferably, enough water resistantmaterial is applied to the powdered material so that the surface iseffectively coated. Then, the cap 32 is replaced, and the container isagitated. Then, the cap 32 is removed and the steps of spraying,capping, and agitating are repeated until substantially all of thepowdered material 34 has been treated.

As will be understood, the effective amount of water resistant materialadded to a container of powdered material will depend upon the size ofthe container. However, with an 8 (eight) ounce container of powderedmaterial, it has been determined that an effective amount of waterresistant material is in the range of about 0.5 to 4.0 ounces, andpreferably in the range of about 1.0 to 3.0 ounces. It will also beunderstood that the aforementioned effective amount may differ betweenpowdered materials manufactured by different companies, which mayproduce their powdered materials according to their own formulae, andmanufacturing standards. Note that effective amounts may also beinfluenced by environmental conditions.

FIG. 4 illustrates a process by which an improved snap line is treated.Here, a container 40 is depicted as having its cap 42 removed to exposewater resistant material 44 contained therein. A line 20 is then addedto the container 40 so that it may be sufficiently coated. After theline 20 has been sufficiently coated, it is removed and allowed to airdry, or dried by applying gentle heat. Alternatively, water resistantmaterial may be applied to a line 20 by spraying the water resistantmaterial directly onto the line (similar to the method of application astaught in FIG. 3).

FIG. 5 illustrates a preferred method by which an improved powderedmaterial may be treated. For this, a separate container may be provided,although it is preferred to use the container in which the powderedmaterial was originally packaged. Then, the water resistant material isadded to the container. As mentioned above, for an 8-ounce container, aneffective amount of water resistant material is in the range of about0.5 to 4.0 ounces, and preferably in the range of about 1.0 to 3.0ounces. Then, the powdered material and the water resistant material aremixed. This can be achieved in numerous ways, such as, for example, bystirring, agitating, or by capping the container and vigorously shakingthe container. Then, the mixture is dried. This step, too, can beachieved in numerous ways. For instance, the mixture could be allowed toair dry, or it could be gently heated. Finally, the mixture is combinedwith a snap line by adding it to a snap line apparatus.

It will be appreciated that the improved powdered material may beproduced in a third container, if desired. In this variation, the waterresistant material may be added first and then the powdered material maybe added.

FIG. 6 illustrates a preferred method by which an improved snap line maybe treated. For this, a separate container may be provided, although itis preferred to use the container in which the water resistant materialwas originally packaged. Then, the line is added to the container sothat it is effectively coated. Then, the line is withdrawn from thecontainer and dried. This can be achieved in a number of ways. Forexample, by air-drying, by forced air-drying, or by gently heating.Finally, the improved line installed into a snap line apparatus, whereit may be combined with the improved powdered material.

It will be appreciated that the improved snap line may also be treatedin a third container, if desired. In this variation, the untreated linemay be added first and then the water resistant material may be added.
